A1 Mini Corner Bracket with Magnets

I have my A1 Mini on a metal table; I designed a small right angle support that has magnets in it to hold the Mini in place. The printer tends to walk while in use. I've included holes for 6x3mm magnets, 7 per bracket. They press fit in with a little effort. The bracket works on all 4 corners. It's a tight fit with the power button in the back but it still works. Please let me know if you'd like any changes.
